The Ornamental Plant Germplasm Center (OPGC) is part of the National Plant Germplasm System, a network of organizations and people dedicated to preserving the genetic diversity of crop plants.

The OPGC is a joint effort of the USDA-ARS and The Ohio State University's Department of Horticulture and Crop Science.  Financial support is provided through the Floriculture and Nursery Research Initiative of the ARS.
